Documentation for C compiler/linker

All of the documentation, that you're interested in, can be browsed to from within the IDE (from the Help menu) or you can just point your browser at:

<nios2_install>/documents/index.htm

For the specific questions you have:

1. Yes, the compiler supports C++.

- Ecos is written using C++ and it is ported to Nios II and uses the identical GCC toolchain.

- Be sure that your C++ code has a file extension of .cpp [perhaps, other extensions will work as well?] or (I think) the IDE won&#39;t handle it correctly.

2. The floating point library details can likely be found in the documentation on newlib.

Best of luck,
